Description

  The present invention relates to boards. More particularly, the present invention relates to a board used as a building member.

  Boards used as architectural members include those of various materials, such as gypsum boards, calcium silicate boards, and wooden boards. Such a board is fixed to a stud such as a wall or a ridge of a ceiling with screws or nails. However, these boards have a certain size (for example, a so-called 3 × 6 plate of 90 mm × 1800 mm), and the surface thereof is not provided with a mark or the like at the time of hitting a screw or the like. For this reason, the intervals and positions of the screws and the like at the time of fixing to studs and the like with screws and the like largely depend on the sense and experience of the operator. In other words, it is said that the accuracy in constructing these boards depends on the skill of the craftsman who is the worker.

  Then, in order to solve the above-mentioned problems, boards provided with marks for driving screws or the like on the board surface have been proposed (for example, Patent Documents 1 to 7).

  Patent Literatures 1 to 7 disclose a board with a mark in which a mark is formed with ink or the like on the surface of a board used as a sublayer of a building interior. For this reason, if these boards are used, using the marks provided on the surface of the boards as a guide, regardless of the skill of the craftsman at the time of construction, it will be properly screwed at the specified intervals or positions in the design And the like can be performed.

It is a schematic explanatory view of surface 10s of B. It is a schematic explanatory view of the construction situation of board 10 of this embodiment. FIG. 4 is a schematic explanatory diagram when a pattern D is applied to a surface 10 s of a base material B of the board 10 of the present embodiment. FIG. 4 is a schematic explanatory diagram in a case where a mark M of a board 10 of the present embodiment is formed of a material containing a fluorescent substance corresponding to different peak wavelengths.

  The board of the present embodiment is a member used as an architectural member, and has a feature in that a mark serving as a reference for fixing the board on the board surface is raised only during construction. I have.

The board of the present embodiment (hereinafter simply referred to as a board) is not particularly limited as long as it is a plate-shaped member used as a building member. For example, a plaster board (so-called gypsum board) used as a base material for walls, floors, ceilings and the like, a plaster board (so-called gypsum board) used for interior and exterior, a decorative board, a calcium silicate board, a decorative plaster board, and the like can be given.
The material of the board is not particularly limited. For example, various materials such as gypsum, wood, resin, metal and the like used as the material of the building member can be mentioned.

The size and shape of the board are not particularly limited.
For example, when a board is used as a commonly used base material, one having a length of 910 mm × width of 1820 mm, a length of 910 mm × width of 910 mm, a length of 910 mm × width of 455 mm, a size of 3 × 8, Various sizes and shapes such as 3 × 9 can be formed according to the construction site. For example, when used as a decorative board, it can be formed to be 910 mm long × 1820 mm wide or 910 mm long × 2720 mm wide.

  The fixing member for fixing the board is not particularly limited as long as it can fix the board to a frame member such as a pillar constituting a base such as a wall. For example, a screw, a nail, or the like can be used as a fixing member for fixing the board.

  In addition, the mark of the board is fixed to a frame member such as a pillar that forms the foundation of the construction site such as a wall of the board (for example, a pillar or stud for a wall, a rim of a body, a ceiling for a ceiling, etc.). The shape and the like of the member are not particularly limited as long as it becomes a reference for appropriately striking the member. For example, the mark may be a grid shape or a dot shape, and the dot shape may be various shapes such as a circle or a cross.

  Still further, the situation in which the marks are arranged on the surface of the board is not particularly limited, and the fixing member can be appropriately driven according to the dimensions of the frame member to be installed (for example, the center-to-center distance between adjacent studs). It is provided as follows. The marks are desirably arranged so that the fixing member can be driven at a predetermined interval or position in design.

  For example, a board is formed so as to be a rectangular plate-like member, a vertical line is formed on the surface thereof along the long axis direction, and a horizontal line is formed so as to be orthogonal to the vertical line, thereby forming a square mark. On the surface of the board. Then, the board is mounted such that the back surface of the board is in contact with the frame member of the wall so that the short-axis side of the board is horizontal. At this time, when the size between adjacent frame members (for example, between adjacent studs) is 455 mm, the length of one side of the square is formed to be 455 mm. Then, by hitting the fixing member on the basis of the vertices of the marked squares, the fixing member can be appropriately hit on the frame member.

  Similarly, in the frame member constituting the base of the wall, if the dimension between adjacent frame members is 303 mm, the length of one side of the square may be formed to be 303 mm. Similarly, when the board is mounted on the ceiling, the length of one side of the square is 303 mm when the dimension between adjacent frame members is 303 mm in the frame member constituting the base of the ceiling. do it.

  In the following description, a case where the board is mounted on an interior wall will be described. Specifically, the wall includes a base and a cloth provided on the surface of the base material of the base, and the base includes a frame member and a base material fixed to the frame member. I have. In the following description, a case where the board of the present embodiment is used as the base material will be described as a representative.

  The board of the present embodiment used as the base material will be described by taking as an example the case of a gypsum board generally used for interiors as its material. In addition, as for the size, a case where a commonly used one having a length of 910 mm and a width of 1,820 mm is used will be described as a representative. In the frame members constituting the wall, the dimension between adjacent frame members (for example, between studs and the rim) is the dimension used in the standard interior construction method (in the following description, all are 455 mm). Will be described as a representative.

<Board 10 of the present embodiment>
The board 10 of the present embodiment (hereinafter, simply referred to as the board 10) will be described with reference to the drawings.

First, an interior wall to which the board 10 is attached will be briefly described.
In FIG. 2, this wall is formed of a frame member including a plurality of columns, studs, and a rim. Specifically, the frame member has a plurality of pillars and studs erected along the vertical direction such that each dimension is 455 mm. A plurality of body edges are provided so as to have a size of 455 mm so as to be orthogonal to the axial direction of these pillars and studs.

Next, the board 10 will be described.
As shown in FIG. 1, the board 10 includes a plate-shaped base material B and a mark M provided on a surface 10 s of the base material B.
In the following, the surface 10s of the substrate B of the board 10 may be simply referred to as the substrate surface 10s or the surface 10s of the board 10.

(Base material B of board 10)
The base material B of the board 10 has a plate-shaped middle material formed of gypsum, and paper is adhered to the front and back of the middle material. That is, the surface of one piece of paper is the base surface 10s of the board 10. Then, as shown in FIG. 1, a mark M which is a reference for fixing the board 10 to a fixing destination member with a fixing member N such as a screw or a nail is provided on the base surface 10s.

(Mark M)
The mark M provided on the base material surface 10s is formed of a material that emits light that can be visually recognized by human eyes when irradiated with light including ultraviolet rays.

Specifically, the mark M is made of a material which cannot be recognized by ordinary light (for example, light of a home fluorescent lamp or LED lamp, sunlight, etc.), but which can be visually recognized by irradiation with ultraviolet rays. Have been. More specifically, the material forming the mark M includes a substance (hereinafter, referred to as a fluorescent substance) that emits visible light (fluorescence) that can be visually recognized by humans when irradiated with ultraviolet rays. is there.
Such a fluorescent substance is not particularly limited as long as it has the above function (that is, it absorbs ultraviolet light and emits fluorescence). For example, a fluorescent substance that absorbs ultraviolet light in a wavelength band of about 315 nm to 400 nm and emits fluorescence can be used as a material for forming the mark M.
Note that ultraviolet light refers to electromagnetic waves in a wavelength band of about 10 nm to 400 nm.

Note that it is preferable to use, as the fluorescent substance contained in the material of the mark M, a substance that makes it easy for an on-site worker to visually recognize when irradiating light including ultraviolet rays.
For example, the light that irradiates the base surface 10s of the board 10 so as to make the mark M visible can be one that contains ultraviolet light but does not contain visible light. In this case, while the fluorescence emitted from the fluorescent material of the mark M is easily visible, the emitted light is in a state where the visible light is hardly included, so that the pattern of the substrate surface 10s is difficult to recognize. Become. For this reason, even if the intensity of the fluorescence emitted from the fluorescent substance is weak, an advantage is obtained that the operator can easily recognize the mark M.

In addition, “not visible” with ordinary light means that the mark M cannot be visually recognized by the ordinary human eye when irradiated with light including ultraviolet rays, and can be visually recognized by the normal human naked eye. A difficult state.
On the other hand, when it is irradiated with ultraviolet light, “visible” means that the mark M can be visually recognized with ordinary human eyes when irradiated with light including ultraviolet light, and that the mark M This is a concept that includes a state in which a state different from the base material surface 10s can be visually recognized to the extent that it can be recognized.
That is, when the substrate surface 10s of the board 10 is irradiated with light including ultraviolet rays, if the mark M is recognized on the substrate surface 10s, the mark M can be visually recognized.

Since the board 10 of the present embodiment is configured as described above, the mark M provided on the surface 10s of the base material B of the board 10 can be visually recognized by irradiating light including ultraviolet rays during construction (FIG. 1).
Therefore, if the operator strikes the fixing member on the basis of the mark M, the operator can appropriately strike the fixing member against the frame member. That is, since it is only necessary to hit the fixing member along the mark M, the board 10 can be appropriately constructed regardless of the skill of the operator.

In addition, since the mark M is not visible in everyday light, even if the mark M is provided on the surface 10s of the base material B of the board 10 in a state where the board 10 is installed, the design property of the base material surface 10s is not affected by the mark M. Has no effect.
For this reason, as described later, even when the work is performed with the base material surface 10s of the board 10 exposed, the work can be performed without worrying about the mark M. In other words, the board 10 is not limited to use as a base material, but can also be applied to a decorative board or the like whose surface is exposed.
In particular, when used as a decorative board or the like, even if a pattern (corresponding to the symbol D in FIG. 4) is applied to the base material surface 10s of the board 10, the board 10 can be properly fixed with the fixing member. In addition, it is possible to make the mark M not affect the design of the substrate surface 10s. Details will be described later.

(Details of mark M)
Hereinafter, the mark M will be described in detail.
The formation and size of the mark M are not particularly limited as long as the mark M serves as a reference when the fixing member N is struck against the wall frame member as described above.
For example, the mark M may be formed in a grid shape as shown in FIGS. 1 to 4, or may be formed in a plurality of dots spaced at a predetermined interval.

In the case where the mark M is formed in a plurality of dots, the dots corresponding to the base frame member are connected with a pencil or the like in a state where the mark M is attached to the wall, regardless of the size of the frame member (for example, between the studs and the trunk edge). (Even if the distances are different from each other), it is possible to appropriately strike the fixing member to the frame member.
For this reason, the board 10 can be appropriately fixed by the fixing member regardless of the dimensions of the frame member of the construction destination, so that the flexibility of the construction can be improved.

  Further, the mark M may be in a square shape as shown in FIGS. Specifically, as described above, a plurality of vertical lines Mv and a plurality of horizontal lines Mh form a grid. At this time, as shown in FIG. 1, a plurality of vertical lines Mv are formed at predetermined intervals along the axial direction of the base material B, and at predetermined intervals so as to be substantially orthogonal to the vertical lines Mv. A plurality of horizontal lines Mh are formed. With such a configuration, the mark M can be formed in a square shape as shown in FIG.

When the mark M is formed in a grid pattern, as shown in FIG. 2, the distance between the adjacent vertical lines Mv and the distance between the adjacent horizontal lines Mh are determined by the distance between the studs that are the frame members and the distance between the rims. It is desirable to form them so as to have a distance substantially the same as the dimension of.
For example, as shown in FIG. 2, the distance between the vertical lines Mv of the mark M is formed to be 455 mm, which is the same as the dimension between the adjacent studs of the frame member, and the distance between the horizontal lines Mh of the mark M is the frame. The member is formed so as to have a dimension of 227 mm between adjacent body edges.
In this case, as shown in FIG. 2, if the board 10 is mounted so that the back surface thereof is in contact with the frame member of the wall and both ends of the board 10 in the long axis direction are located on the surface of the pillar, the vertical line The intersection Mi where the Mv and the horizontal line Mh intersect can be located near the approximate center line of a frame member such as a pillar.

In addition, if the fluorescent substance contained in the material of the mark M of the board 10 has the above function, it may have the function of exhibiting the phosphorescence phenomenon.
This phosphorescence phenomenon is a phenomenon in which light returns slowly to the ground state over a certain period of time even after the irradiation of ultraviolet light is stopped. Therefore, if a fluorescent substance having such a property, that is, a phosphorescent property is included as a material of the mark M, the mark M can be visually recognized for a certain period of time even after the irradiation of the ultraviolet rays is stopped, so that the work efficiency can be improved. it can.

  Further, the material of the mark M may include two types of fluorescent substances as described above. In this case, a mark M of a different shape can be displayed on the base surface 10s of the board 10 of the present embodiment only by adjusting the wavelength of the ultraviolet light to be irradiated.

For example, as shown in FIG. 4, the substrate surface 10 s of the board 10 responds to an ultraviolet ray having a peak wavelength (for example, a peak wavelength of 365 nm) in a wavelength band of 350 nm to 370 nm (hereinafter, referred to as a first wavelength region) ( In other words, a fluorescent substance that emits fluorescence by such ultraviolet light) and a fluorescent substance that responds to ultraviolet light having a peak wavelength (for example, a peak wavelength of 380 nm) in a wavelength band of 375 nm to 390 nm (hereinafter, referred to as a second wavelength region) are included. The mark M is formed of the material.
In this case, if light containing ultraviolet light in the first wavelength region is irradiated, fluorescence in response to ultraviolet light in such a wavelength band is emitted, and a desired mark MA can be displayed on the base surface 10s (FIG. 4 shows a lower mark). Side right figure).
On the other hand, when light containing ultraviolet light in the second wavelength region is irradiated, fluorescence in response to ultraviolet light in such a wavelength band is emitted, and a desired mark MB can be displayed on the base material surface 10s (in FIG. 4, the lower side). Left figure). In other words, if the light L for displaying the mark M is capable of irradiating the ultraviolet rays in both wavelength bands, the marks MA and MB having different shapes can be formed on the board 10 only by changing the wavelength band of the light source L. Can be displayed on the base material surface 10s.

  The peak wavelength in the first wavelength region corresponds to the absorption peak in the first wavelength band described in the claims, and the peak wavelength in the second wavelength region described above corresponds to the second wavelength in the claims. The band corresponds to the absorption peak.

In addition, the display adjustment of the marks MA and MB can be easily performed only by adjusting the light source L. For this reason, the mark M corresponding to the dimension may be adjusted with the light of the light source L according to the dimension of the frame member. The board 10 can be appropriately fixed by the fixing member N.
That is, if the mark M is provided on the substrate surface 10s of the board 10 so as to correspond to the dimensions of the plurality of frame members, the board 10 can be appropriately fixed regardless of the construction location.

  In addition, the fluorescent substance included in the material of the mark M is not limited to the above two types. For example, if a fluorescent material that responds to ultraviolet light in a wavelength band in which the peak wavelengths do not overlap as much as possible is included, a plurality of marks M of different shapes are further displayed on the substrate surface 10s of one board 10 by the applied ultraviolet light. Will be able to do it.

  In addition, the material forming the mark M may include various substances such as an adhesive and a paint, in addition to the above-described fluorescent substance, but is blended so that the mark M is hardly visually recognized by ordinary light. It is desirable.

(Light source L)
The light source L that irradiates ultraviolet light for making the mark M visible to the human eye can emit ultraviolet light in a wavelength band that can excite a fluorescent substance contained in the mark M and emit fluorescence. If it is a thing, it will not be specifically limited.

  As such a light source L, for example, a known ultraviolet light or an ultraviolet LED light (UV-LED light) can be adopted. Many UV-LED lights L that emit ultraviolet rays in a wavelength band generally referred to as UV-A (a wavelength band of about 315 nm to 400 nm) are commercially available.

  In addition, there are many UV-LED lights L in which the wavelength band of the emitted ultraviolet light is determined to some extent. Specifically, some are designed so that the emitted ultraviolet light has a specific peak wavelength. For example, the UV-LED light L emits ultraviolet light having a plurality of peak wavelengths (e.g., ultraviolet light in a first wavelength range, ultraviolet light in a second wavelength range). There is a structure that can switch irradiation of ultraviolet rays in a wavelength region. For this reason, when the mark M is formed of a material including two kinds of fluorescent substances that respond to the ultraviolet light in the first wavelength region and the ultraviolet light in the second wavelength region, as shown in FIG. By simply adjusting the wavelength band of the emitted ultraviolet light, a mark M having a different shape can be displayed on the base surface 10s of the board 10. In other words, if a fluorescent material that reacts to ultraviolet light in a specific wavelength band is adopted as the material of the mark M, it is possible to form the mark M that reacts to various kinds of ultraviolet light, but the details will be described later.

  Moreover, since various types of UV-LED lights L capable of emitting ultraviolet light having such a specific peak wavelength are commercially available, there is an advantage that a usable light source L is easily available.

  As shown in FIG. 1, when the light source L is turned on to irradiate the base material surface 10 s of the board 10, the fluorescent material contained in the mark M emits fluorescence as described above. The state of the mark M provided on the substrate surface 10s can be properly grasped. That is, on the base surface 10 s of the base material B of the board 10, the mark M (the state of (A) in FIG. 1) that could not be visually recognized by ordinary light is turned on by the light source L so that the mark M can be visually recognized. ((B) in FIG. 1).

  The UV-LED light L used as the light source L has various shapes, but may have any shape as long as it has the above function. For example, it is possible to employ not only a fluorescent light type and a penlight, but also a device that emits light such as a so-called black light when the light source L is turned on, but is not limited thereto. .

  Note that the light source L desirably emits only predetermined ultraviolet light. In this case, since the light emitted from the light source L does not include visible light, the fluorescence emitted from the fluorescent material of the mark M can be easily recognized.

For example, when the work place where the board 10 is constructed is an indoor place, the normal work is performed by illuminating a general work light. With such general work light, when the pattern D is applied to the surface 10 s of the base material B of the board 10, the pattern D is in a visible state, while the surface of the base material B is visible. The mark M provided at 10 s is not visually recognized (see FIG. 3A).
In this state, that is, when the work light is turned on and the light source L is turned on, the pattern D and the mark M are visually recognized in a disturbed state on the surface 10s of the base material B of the board 10, so that the mark M is difficult to see. Become.
However, if the work site is a place where it is difficult for visible light to enter as described above, turning on the light source L with the work light turned off reduces the amount of light containing visible light from the surroundings. The mark M can be easily recognized even if the pattern D is provided on the surface 10s of the mark.
For this reason, even if the pattern D is provided on the surface 10s of the base material B, the operator can appropriately visually recognize the mark M, so that the board 10 can be appropriately fixed. .

  Moreover, even when the work is performed in a state where the base material surface 10s of the board 10 is exposed, the mark M does not react with ordinary light, so that the design of the surface 10s is not affected. For this reason, the board 10 is not limited to use as a base material, but can be applied to a decorative board or the like whose surface is exposed.

Further, the light source L having the above function may be mounted on a drill used for fixing a screw or the like. Specifically, when the light source L is turned on in a state where the light source L is mounted on the drill, the light UVL to be emitted is emitted toward the tip of the driver (that is, the axial direction of the bit attached to the chuck of the driver). Installing.
In this case, compared to the case where the entire board 10 is irradiated, it is possible to reliably prevent the light UVL including the ultraviolet rays from being blocked by the operator. For this reason, since the mark M at the time of driving a screw or the like can be visually recognized with certainty, work efficiency can be improved.

(Example of construction of board 10)
Hereinafter, a description will be given of an example in which the board 10 is installed as a base material of a wall base.

  First, as shown in FIG. 2, the board 10 is arranged so that the back surface thereof is in contact with the frame member of the wall. At this time, the board 10 is arranged such that one edge in the long axis direction (the right long axis edge of the right board 10 in FIG. 2) is located substantially on the center of the pillar. In this state, the mark M is not visually recognized by the human eye on the base surface 10s of the board 10 (see FIGS. 1A and 2B).

  Then, as shown in FIG. 2A, in a state where the board 10 is installed as described above, the light source L that emits light including ultraviolet light is turned on to include ultraviolet light toward the substrate surface 10s of the board 10. By irradiating the light UVL (see FIG. 2A), as shown in FIG. 2A, the operator can visually recognize the square mark M provided on the base surface 10s of the board 10. become able to.

  The operator fixes the board 10 by hitting a fixing member N such as a screw on the basis of a square mark M provided on the base surface 10 s of the board 10. Specifically, in the mark M, the intersection Mi where the vertical line Mv and the horizontal line Mh intersect is a reference for hitting the fixing member N such as a screw. 10 can be properly fixed to the wall frame member. Moreover, the intersections Mi are provided at predetermined intervals or positions in design as necessary.

  Therefore, even if the worker does not have special skills or experience, the fixing member N such as a screw can be appropriately hit, so that the board 10 can be appropriately constructed regardless of the skill of the worker. In addition, since the mark M has a square shape, the fixing member can be hit straight by simply hitting the fixing member based on the intersection Mi, so that the accuracy of the screwing or the like can be improved. Further, since it is not necessary to provide a mark as a reference for hitting the fixing member N such as a screw at the construction site, the workability can be improved.

  Moreover, since the mark M is not visually recognized by ordinary light, even if the cloth is adhered to the base material surface 10s after the board 10 is used as a base material, the mark M does not seem to be seen through the cloth surface. For this reason, even if the cloth has a small thickness, it can be stuck without worrying about the mark M, so that the degree of freedom of the cloth (that is, the degree of freedom of interior decoration) can be improved.

(Method of providing mark M on base material surface 10s of board 10)
The method of providing the mark M on the substrate surface 10s of the board 10 is not particularly limited.
For example, the mark M may be marked on the surface 10s of the base material in accordance with the base material of the construction site at the construction site by making the material containing the fluorescent substance into an ink, but the mark M is printed on the surface 10s of the base material in advance. It is desirable to do. If the mark M is formed by printing, the board 10 of the present embodiment provided with the mark M having a size corresponding to the intended use can be easily formed in large quantities.

  Such a printing method is not particularly limited. For example, a known printing method such as flexographic printing, gravure printing, offset printing, gravure offset printing, flat plate offset printing, dielin printing, letterpress printing, intaglio printing, jet printing, silk screen printing, or electrostatic printing can be employed.

  In addition, when gypsum board is used as a material of the base material B as described above, paper or the like is bonded to the front and back sides, and the base material B may be manufactured using a material in which the mark M is previously put on the paper. Alternatively, the mark M may be printed on the surface 10s of the base material B on which paper or the like is bonded.

  The board of the present invention is suitable as an architectural plate member.

The board of the first invention is a board used as a base material of an architectural wall, and a mark is provided on the surface as a reference when fixing the board, and the mark is a first wavelength of ultraviolet light. A first mark including a first material having an absorption peak in a band and a second mark including a second material having an absorption peak in a second wavelength band of ultraviolet light are provided .
In the board of the second invention, in the first invention, the first mark is provided on a surface of the board so as to be located on a pillar and a stud of the base frame member in a state where the board is installed. The second mark is provided on a surface of the board so that the second mark is located on a body edge of the base frame member when the board is installed .
The board of a third invention is characterized in that, in the second invention, the first wavelength band is a wavelength band of 350 nm to 370 nm, and the second wavelength band is a wavelength band of 375 nm to 390 nm .
